Wood plastic composite materials can be divided into polyethylene, polypropylene, polyvinyl chloride, ABS plastic and plasticized wood materials according to different plastics; they can be divided into wire, profile, sheet, sheet and foreign material according to different forms of products; According to different manufacturing processes, it can be low foaming, medium foaming, hollow structure and solid material; it can be divided into structural type, decorative type and special type according to different performances.
Because wood plastic composite materials combine the characteristics of wood and plastic, they have the following excellent characteristics:
(1) It is resistant to insects, corrosion, ageing, water absorption, water absorption and deformation, and long life; (2) Appearance is similar to wood material, better than wood dimensional stability, no cracks, warpage and other defects, and no wood scar; similar to wood secondary processing, can be cut, pasted, can be fixed with hardware connectors; (3) The surface of the product is smooth, flat and strong, and can suppress the three-dimensional pattern and other shape requirements. Various colouring agents or coatings can be added to produce various colourful products with good decorative effect. (4) It has the higher hardness than plastic, has thermoplastic processability, can be reused and recycled, is also biodegradable, and is environmentally friendly. Wood plastic composites are widely used in construction products, such as flooring, siding, building formwork, door and window profiles, guardrails, blinds and roofing panels; in the automotive industry, such as interior trim panels, driver glove boxes, Spare tire cover, seat backing, roof lining, etc.; packaging and transportation, furniture, garden landscape, interior decoration, office equipment and sports equipment.
